One common theme is the exploration of their different personalities coming together. Tanjiro is very kind - hearted and Shinobu has a more complex, somewhat mysterious nature. Fanfics often show how they bridge that gap.
There are fanfictions where Shinobu and Giyuu are paired in a post - demon - slaying world. For example, they might start a new life together, perhaps helping to rebuild the demon - slayer corps in a different way. Shinobu's medical knowledge and Giyuu's combat skills could be combined in interesting ways in these stories.
You can find 'demon slayer shinobu x giyuu fanfiction' on popular fanfiction websites such as Archive of Our Own (AO3). There are a large number of fan - created stories there, and you can search for specific pairings like Shinobu and Giyuu. Just type in their names in the search bar and you'll get a list of relevant fanfictions.
Another great one is 'Tanjiro and Shinobu's Journey'. In this, they go on a journey together that tests their relationship. It shows how they support each other through tough times, and it's full of action and emotional moments that make it an engaging read.
Another theme is mentorship. Shinobu, being more experienced, often acts as a mentor to Tanjiro. She imparts her knowledge about demons and fighting techniques. This is seen in quite a few fanfictions where Tanjiro looks up to Shinobu for guidance.
The plot could involve the reader being a new Demon Slayer. Shinobu takes the reader under her wing to train. They could go on missions together, and the reader slowly discovers Shinobu's kind heart beneath her often - aloof exterior. Along the way, they face various demons and grow closer as friends and comrades.
To write their relationship development, consider their different personalities. Shinobu is calm and collected, while the reader can have various personalities. If the reader is shy, Shinobu can take the lead in conversations. As they face challenges together, like fighting a powerful demon, their trust in each other will grow. You can also add some light - hearted moments, such as cooking together in the Butterfly Mansion, which will make their relationship more multifaceted.
Their relationship can be further explored by focusing on their non - verbal communication. Since Nezuko can't speak much as a demon, the looks they exchange, the way Tanjiro gently touches her head to reassure her, these small gestures can be delved into. For example, in a dangerous situation, Tanjiro's glance at Nezuko could convey a whole world of trust and protection.
A great plot idea could be that Nezuko develops a new power that only works when she and Tanjiro are in close proximity. This power could be crucial in fighting a powerful upper - rank demon. For example, she might be able to create a protective shield around them both. Another could be a fanfiction where Tanjiro and Nezuko are invited to a demon slayer gathering in a far - off land. There, they meet other slayers from different regions and learn new techniques. Along the way, they also have to deal with some demons who are trying to infiltrate the gathering.
